Harry Potter & the Codex of Corruption [Ch. 10] By The Merry Mage

The Merry Mage Games released a new game called Harry Potter & the Codex of Corruption and the version is Ch. 10. The game’s story is about You play Harry Potter and you’ve just acquired a dangerous manual of dark sex magic. The spells start out naughty, like letting you see through a girl’s clothing. But as you progress, the spells become more twisted and depraved. Explore your darkest cravings and compel the girls to satisfy them all. But be careful or you’ll end up dead, expelled, or consumed with darkness!

This interactive series is a parody and is for right hand entertainment purposes only. All artwork is original. All characters in the game are 18+ years of age.

Developer Notes:

Gameplay Style
In this choose-your-own-adventure style game, you’ll navigate through the world of Hogwarts, finding girls and trying out different dark sex magic spells on them.

As you progress, you’ll learn spells like:

  • Transpericum – uncovering what is hidden (under their clothes that is!)
  • Membrum spectrus – better known as ghost cock…
  • Ejaculum faminus – making the target crave your cum
  • Servum sexualus – making the target your sex slave…

You’ll see the results of the spells in a mix of images, videos, and interactive modules.

The Characters So Far…
Here’s four of the characters I’ve created so far for the game.
Starting with Chapter 6, I use a hyper-realistic and improved model of Hermione.
Some of the original characters include Hailey and the host of The Nightly Show, Aurora Glimmerstone. ; p
